摘要

Background: Cancer has been the leading cause of death in Taiwan since 1982. Therefore, pain control in palliative care has recently become more important. Patient- controlled analgesia (PCA) is a common technique in cancer pain management. The present study was undertaken to evaluate the accuracy and safety of an elastomeric pump as a PCA infusor during long-term infusion.
Methods: Ten disposable analgesic devices (Baxter® Basal-Bolus Infusor-15) with a continuous infusion rate of 0.5 ml/hr were used in this study. Each elastomeric balloon was filled with 60 ml of isotonic normal saline solution. The outflow of saline solution was collected in a volumometer with evaporative protection. The infusion volume was checked every 24 hours for 35 days. Fifty ml of normal saline was refilled into each balloon at the end of days 3, 8, 13, 18, 24 and 30. The environmental temperature was kept at25±1℃.
Results: The highest mean infusion rate was 11.4±0.77 ml/day on day 5 and the lowest mean was 7.4±0.41 ml/day on day 35. (P＜0.0001) A significantly higher mean infusion rate was noted at the end of the next day after each refill (P＜0.001) and it decreased gradually afterward. The infusion rate of the Baxter infusion was more accurate (mean 11.4-8.4 ml/day) during the first 2 weeks, and a fairly accurate rate was found for the following 2 weeks (mean 11.1-8.0ml/day), but poor accuracy occurred after this.
Conclusions: A Baxter® basal-bolus infusor-15 provides satisfactory accuracy and safety during long-term infusion in chronic cancer pain management within 6 refills or a 4 weeks duration.
